This may be slightly off-topic but I bought realMyst on Steam without knowing what I was getting into: I was expecting it to be a game download, but it's not.Steam needs to run (online) in order for you to be able to play games you've bought there. There is also an off-line mode but this doesn't work for all games.If I had known in time what "DRM free" means I would never have purchased through Steam, now I have the feeling I bought something that isn't mine

Additionally: at first realMyst didn't run on my Macbook Pro 8gig with OS 10.10.2but later I found out this is because Steam only runs from the topfolder in my global application folder and realMyst only works when I install it in the users' application folder.Weird.But maybe this can be of help for someone.
